Have you recently heard people talking about being over-acidic, measuring their pH and eating alkalizing foods? Emphasizing the importance of body’s pH might seem like a new fashion, but the science and art of pH balancing has had a long tradition and, unlike some other trendy theories, it has successfully overcome the test of time.
In terms of chemical understanding, pH is a measurement of hydrogen ion (H+) concentration in a solution. Solutions with low hydrogen concentrations have high pH values, and solutions with high hydrogen concentrations have low pH values. As you probably remember from school, the pH scale runs from 1 to 14, with 7 representing the pH of pure water – neutral. Above 7 is alkaline, below is acidic.
